ATS provides a variety of thermoelectric assemblies and modules for air-to-air, air-to-plate, and air-to-liquid applications. These semiconductor devices utilize the Peltier effect to create heat flux between surfaces. By applying a DC current, the module can either cool or heat, depending on the current’s direction. A thermoelectric cooler (TEC) acts as a solid-state heat pump, transferring heat from one side to the other against the temperature gradient.
